How To Clean an EGR Valve Without Removing It
Вставка
- Опубліковано 20 тра 2024
- In this episode of Driveway Dudes, Paul and Will shows you how to clean your EGR (Exhaust Gas Recirculation) Valve, Inlet Manifold and Inlet Valves without removing any of them.
This is a home experiment and an unbiased use of JLM Diesel Air Intake & EGR Cleaner. Similar products are available.
This product is designed to dissolve carbon deposits, gum and varnish build up. It should restore air flow to the engine thus improving power and acceleration while reducing exhaust smoke.
Paul & Will did their best to follow the instructions on the can. They adjusted the throttle and amount sprayed accordingly.
This product is a hazardous material, it is extremely flammable and harmful to skin, lungs and eyes. We strongly recommend wearing gloves and eye protection. Please read the instructions and warnings carefully.
If you cannot get direct access to the turbo an alternative would be to spray (less effective) into the air duct in the direction of the turbo but please remember to remove the MAF (mass airflow)/air intake sensor first as the cleaner may damage it.

I'm a diesel mechanic and can tell you now that your wasting your money trying to clean the valve with that stuff....!!!
The only way to clean correctly is to remove the valve and clean it by hand , soak it in paraffin overnight and then dry it off and then get a tin of spray on oven cleaner and thoroughly coat the valve , leave it to work in for a couple of hours and then get a toothbrush and give it a good scrub and it will look like new.....👍
Yes, we did that also

Bro,whts the cleaning interval of this eye in ford figo 1.4 tdci?
These guys are Irish ! , what do you expect ! :P
Thankyou
@@gary9432 they didnt invent the product. They are just showing how to use it based on the manufacturers instructions.
Engineers should start adding a small access port to the egr system for preventative maintenance.
Should it be right below the main port?
I would put them on the top of problem areas where carbon is most likely to build up and clog allowing you to inject solvent to dissolve the buildup@@rafezetter8003
Thanks for the tip lads, I tried this but it didn't work well at all. I had to take the valve off and soak it in petrol and scrub it. But I shot that stuff into it after cleaning and it's working like new again. Cheers lads.
I have a Toyota 3rd gen Prius and it's Impossible to remove the EGR valve only. What worked was using an extra reach 12 mm racheting wrench for the three Nuts in the back and I had a hard time reaching the 4th HIDDEN 12 mm nut underneath the EGR cooler. Used a Torx E8 socket for the two Bolts ( in the back of EGR cooler) and we finally freed the EGR assembly. Now I can clean the valve and EGR cooler easily. Good video
Been having troubles with my 1.3cdti Vauxhall Meriva of late... laggy turbo, sometimes not boosting at all. Looking into using this style of EGR cleaning (as a recent repair meant I saw a very clogged and grotty EGR system) as well as the turbo cleaner as they seem to be the best tries before drastic action is needed. Vids like this are a great help, appreciate people like yourselves putting them up 👍
Hi Michael. Thanks for the compliment and happy you found this video useful.
We try to be as straight forward and helpful as possible in our videos.
We recommend periodic checks and basic preventative maintenance rather than wait for something to go wrong or become faulty.

Lag is usually due to dirty air mass flow sensor . Buy a cleaner and its an easy clean
Clear explanation of getting this done. Good Visuals (Lighting, etc.) Very Helpful (especially when i am learning how to do this stuff so i will not get over charged by a local repair shop. Man, so many of local shops are questionable (overcharge, misdiagnose problem, misleading info about repairs, etc, etc). Thanks for video (USA).
Hi K,
Good on ya. No better way to learn than to try it for yourself.
Sometimes DIY can stand for Destroy It Yourself but not so in this video. You will not damage anything as long as you do not spray any sensors i.e. Mass Air Flow (MAF) sensor being very sensitive.
If after using the can of EGR valve cleaner the EGR valve is still choked up then it would have just cost you the price of a can to find out.
We have another video of cleaning one when it's out of the car ua-cam.com/video/HXqJ0YcOqOI/v-deo.html
With experience we can relate to different garages and workshops diagnosis and billing methods so we make every effort to do it ourselves and share it with our viewers
Really amazing,
Respect from India.
And the old man is amazing. The way he is supporting the boy is like a pure father son relationship.
I've done this job on my C4GP. I used the Wynns EGR valve cleaner which is about a tenner from Halfords in the UK. With the Wynns you have to use the entire can. I sprayed mine just after the air filter because the Wynns won't harm the MAF or the turbo (my C4GP has the 2.0 HDi engine). I let the car idle and gave it 1 second bursts of spray. The engine note will change and as soon as it recovers give it the next spray and repeat until the can has been used up.
Hi Parknest,
The instructions and application of EGR valve cleaners may differ from brand to brand.
They claim they can clean effectively.
We haven't tried Wynns product but If it worked for you then that's all that matters.
Well done.

I used it today but nothing came out of the exhaust and my eml light is still on?
That's daft, unless you're driving a very old car. The EGR in most modern vehicles won't open unless the engine is under load (revs above 2000). This is because generally engine temps will be relatively low and the risk of valve clatter is minimal. In diesels this is especially true as Diesel engines run colder at idle than petrol ones. I find it pretty unlikely that your issue was the EGR. It's possible that it may have been the throttle body and you were just lucky enough to have managed to free up the valve without having to rev it.
*ggg*g****-------g
After such cleaning, it was good to show what egr looks like, whether it was washed or just splashed
Another video showed that it was pretty useless.
Ha ha
Do display fault lights turn on after egr cleaning for Volvo s 40 2008 model vehicle? with which liquid it makes more sense to clean? Thank you.
Great job guys, indeed useful. The JLM instructional video (today at least that I checked) is saying to not spray it on the turbo as other people are saying, but to the inlet and not on the mass air flow sensor (MAF). On good trick on this car would be to remove the MAP sensor and spray to the hole.
Hi ktopoglidis,
Thanks for the comment.
Instructions and directions released by different brands are usually generalised and not model specific.
It is possible to spray directly through the turbo provided it's not hot.
The spray canister being highly pressurised would be very cold and spraying it into a hot turbo could possibly cause micro fracturing of the vanes.
If as you suggested that removing the MAF and spraying in that way, we would reckon the majority of the spray would hit the inside of the pipe before a very little would eventually find it's way to the EGR valve
indeed they are not model specific the instructions from the manufacturers, but they do say in their video to do not spray in the turbo. There are several reasons, but I don't go into that. For many european models (Citroen, Mazda, Peugeot, Volvo, Mini and possibly more) the engine is the same (or similar). So taking one bolt that keeps the MAP is as easy as taking out the intake pipe.
I will agree that you may have issues of hitting the pipe and run down a bit, but still might be better option.
The JLM video is here also: ua-cam.com/video/rFoZ6F1KESw/v-deo.html
Since I wanted to clean and the pipes etc I sprayed also on the turbo a bit.
We did indeed try it through the MAF/MAP on a Citroen C5 1.6hdi and it didn't work so well for us.
We found this way better but we would recommend caution as described above
That was Great!!!! Love how humble you both were God bless you and yours from Missouri U.S. A.
Lee Brushwood what’s the cleaner u used ?
@@virginiacurcija9445 I used seafoam motor tune-up, but I wasn't having a problem with my E. G.. R. Valve. At the time my truck had carbon built on top of the Pistons, so I just poured some down the carburetor and ran it for awhile. It smoked like a smog machine, but ran like a top afterwards.
How would this spray have made it to the egr valve? The spray would need to go out the exhaust, past the cooler then get to the egr? Even then that is only if the computer had the egr valve open
Hi guys having problems with a 06 transit connect failing the DOE on the emissions now it was lying up for a while just wondering would cleaning the egr valve help to get this passed obviously with the other bits you have to do..ie filter changes diptane ect?
Thank you yet again i owe you both a pint ,i really am grateful ,paul.
Can you send the pint in the post mate?
I've a 1.6 hdi 08 c4 Picasso service light on every time I start engine also says risk of dpf blocking. I've cleaned dpf filled up pats fluid under car. It's still does it. Car is fine in every way driving. Tried clearing message with my dinostic scanner still stays on . Any idea
Two things. One, as soon as you get your intake reassembled, go for a drive, it's best to do a decent 15 minutes at highway speeds to burn up any of the EGR cleaning fluid that's left as residue.
Two, those cleaning sprays work best preventively. That means if you want your diesel engine to last for ages, start doing this every 20 to 30 thousand km from new. If you've bought a second hand diesel, pay to have the intake and EGR valve cleaned, then use this spray to keep it from clogging back up. Or don't, it's your car.
I would hve also cleaned the MAP sensor.
Good advice. Prior to using the spray the engine management light was lit on the dash. After spraying and reassembly it was driven and the light went out. We eventually removed the egr valve and cleaned it. See link below.

Nice tutorial EGR System service 🎉
How do you think your cleaning the egr by spraying in the inlet side of the turbo ??
My citreon dispatch 1.6 2008 engine light has come on, won't go past 40mph.. diagnostic says egr valve, will it be as easy for me to do like you did here? I need my van for work and no garage can change my valve until next week 😫
I have just got some that you put in the tank is this any good
Hello) It turns out that you did the dismantling of the air sensor and poured the spray directly into the turbine and all this went through the air cooler and through the damper and into the motor?
i have a 2007 2ltr vtr deisel with a different engine layout how and where do i put the spray in this model
Thank you for the advice i will start with a bulb first and later a sensor kit ,keep well ,paul.
Will do as i need one thanks Will, paul
Let us know how you get on :)
EGR spray cleaner for gasoline cars isn't available in the United States. What sort of substitute cleaner can I use? Does the product you are using feel very oily if you rub it in between your fingers? Does it evaporate quickly? Does it have the smell of acetone? I've read that adding 2 oz. of automatic transmission fluid per gallon of gas will clean the EGR valve, since it doesn't burn completely and the vapor works its way into the exhaust.
The valve is not in tbe oposite side? There is not the turbo? Where u spray it? How do you clean egr when spray the cleaner into turbo?
Using flammable liquid. Do you think after it detonated there's any product left to do anything or has it added a biproduct to your egr. deisel itself is a pretty good lubricant to clean parts with. Yet its biproduct leaves a black chalk like substance called carbon you used a products biproduct am just wondering if you thought about that
Hello ! What kind of spray did you used in this video?
Did the eml light go out after doing this or did u need to clear the error code manually
Hi guys. Does that alternative works with normal (gas) cars? Since yours is Diesel. I have a Chevrolet Lumina 98.
This video makes the whole job of cleaning the ERG valve look so easy thank you both for this you are true professionals ,paul

What part of the country do you have your garage /workshop in ? please ,my problem is we live in Westmeath far away from a good service garage as your selves, we have many main dealers who make it up as they go ,paul
thank you we appreciate everything you have posted for us ,paul
Hi Paul. We appreciate your desire to bring your Berlingo to us, however we don't have a garage/workshop. We are car enthusiasts that do everything from the driveway, hence why we call ourselves Driveway Dudes :)
Wow thats fantastic ,but how do you manage in our countries daily rain fall ,we have rain nearly every day down here the fields are awash with water ,any way i hope 2018 is a great year for you both and thank you again paul.
Hi, is it good for kia ceed JD 2016 diesel too?
im going to try this, thanx for advice
Might be worth a video on re attaching the bulkhead before you test drive it?
Where to purchase the JLM Diesel Air Intake & EGR Cleaner in Chicago area or in US?
Surely the intake is the throttle body and throttle valve while EGR is exhaust gas recirculation which is outlet?
The EGR gasses come from the exhaust manifold to the EGR valve, back to the intake manifold, into the engine. Remember "EXHAUST Gas Recirculation".
So…. It works right ? Is that the point or ?
Exactly, where they spray will do nothing for egr valve !
@@conorf8091No, it does not work, only way to clean properly is remove EGR valve, these sprays are just temporary fix
@@No-timeforimbeciles yes I found that out the hard way. I over heated the catalyst. I fixed the egr code by fitting an new one properly like you said at least ..
Absolutely true... Am an engineer myself... Fail to understand how this method will help to clean an EGR valve after the cleaner has passed thro the engine , burnt, passed thro catalytic converter, and a small % of those fumes will be routed thro EGR valve , and clean it...!! Pretty optimistic...!!
Does this spray have any side effects that might damage any parts?
Having taken my EGR valve out to clean it, I find it hard to believe a bit of spray will get an EGR restricted with gunk clean. I scraped gunk off my EGR and soaked it in white spirit.
When I put it back there was an increase in power.
Also is it a good idea to have the at least two desert spoons of gunk that were in my EGR to be sucked into the engine?
The chemical composition of the EGR cleaning spray is such that it is capable of breaking down the deposits, ignites with the air fuel mixture and is expelled through the exhaust.
Is Gunk ignitible ? If not then be careful as fluids do not compress well and could possibly harm your engine.
In the very near future we will be making an engine cleaning video, We may use a car or a motorbike, e.g. one of our cars or maybe a Px Arcobaleno that is to be restored.
Hi guys, I have a fiat scudo 2.0l multijet 2009 and my fault codes are coming up egr problem, i was was wondering if you could tell me where to locate my egr valve please?
Thanks for the taking the time to shoot & post the video. I have a 207 1.6 HDi 2011reg. Its the first time I have ever owned a Diesel. I bought it 14months ago and it has 58000. is it worth doing this to my car, it seems to be running fine. Just had a major service on it yesterday by a Peugeot garage! I also only use Shell V-Power and BP Ultimate, alternating between each fill up.
Hi rush man1uk. Thanks for the comment.
We like to think that this periodic preventative maintenance can help so that you may avoid having EGR issues.
Spending £10 - £15 and an hour of your time could potentially save you £hundreds in garage bills.
if you do decide to do it then just be careful that you spray it after the MAF as it is sensitive to the EGR cleaner.
Please feel free to share this channel with your Family, Friends and Contacts :)

Seems like this it worth a try . My old Astra van is on 188000 miles
Thought you sprayed it through the maf sensors end air filter pipe?
Fantastic guys! Just came across you for the first time and LOVED your video. It's amazing to see a little bit of Ireland from the SE of Florida!

Good morning Gentlemen once again a question for you i would like to fit a reversing bleep to my multispace plus 2012 1.6 HDi 90 i notice there are bulbs one can buy that seem to do this ? your suggestions please as i havent a clue what to do but i need a bleeper,thanks Paul.
There are different types of audio reversing bulbs available to buy.
Two things to take into account.
1. The fitment size/shape and 2. Canbus friendly (i.e. your car will accept the bulb and not throw up a fault on the dash.
I have tried some in the past. From experience I have found they don't last very long.
A reversing proximity sensor kit may be a better option. They are inexpensive but installing it may be a challenge for the average diy enthusiast.
Driveway Dudes - Paul
Is it normal for the car temperature gauge to go really high When spraying this ???
Fair play done works very well thanks for making the video lads
Back again Sorry, in the book i got with the car Berlingo multispace plus 2012 it shows rear parking sensors my dont bleep thats if my model has them maybe you would advise me please,paul.
Hi Paul. No need to be sorry. Can you see any round sensors on your back bumper?
Driveway Dudes - Will
Top and bottom of it is the EGR valve needs removing to clean it . That stuff won’t move the soot or tar like gunk that clogs the valve and parts up
I have a307 Peugeot diesel anti pollution message comes up would try this but cannot see same pipe on mine ?
How is that spray going to enter EGR valve? This is intake and goes directly to the intake valves. EGR valve and pipe are not on its pathway.
please delete your video from youtube.. this make no sense
EGR cleaner is a flamable fluid. So if you can spray into the turbo intake, the highest part of the cleaner fluid will burn in the cylinders. Maybe a little can go out to the exhaust system, but the huge part of them will go into the catalysator, and not into the EGR tube.
And i think, that very small burned cleaning fluid will not remove that lots of carbon dust from the EGR valve.
It worked for us and we believe for many more people that have used it.
We didn't manufacture it nor can we say how much will be burned in the cylinders or how much will recirculate.
We made a video to see how effective it was. We followed manufacturers directions of this brand and the result was in our opinion that it did indeed do what it was designed and marketed for.
Our EML was on before we started and afterwards it was not. If just a tiny percentage got through then apparently it was enough to make a difference.
Absolutely! Then consider that only a small percentage of the exhaust fumes get fed back to the egr. Anyone who has ever cleaned an egr valve after stripping it knows how much effort it takes to scrub it clean. There are no short cuts. Strip and scrub! You may want to look inside your inlet manifold while you're busy because i just finished removing about 350 gr of gunk with oven cleaner. Enjoy!
Thanks again.
Hi yet again, how important is it to clean out the small bore metal pipe on the left side of the ERG valve held in place with a alan screw i think it feeds oil to the turbo on my 1.6 HDi 90 Berlingo 2012 version Thank you ,Regards Paul.
Hi Paul. Is it leaking where the Allen Screw attaches the pipe to the turbo? If not, it would probably be best to leave it alone.
no but my garage man feels with 128000 miles on the clock it should be cleaned out ??Thank you Paul.
Im sorry if i put you on the spot this was NOT my intention but if this is important and will help to extend the turbo life then i will go for it ,Sincerely Paul Djerassi.
Hi Paul, You are not putting us on the spot. You are asking for our advice and views and we can offer that. We would never say - you must do this or you must do that.
The 2007 Citroën C4 1.6hdi that Will owns is his daily driver. It has to date over 135k miles, is reliable, pulls strong and can still exceed 55+ mpg.
To his knowledge the turbo has never been replaced.
He is meticulous in his maintenance and servicing of the car i.e. He carries out weekly checks and services the car within the service schedule. He uses the oils, lubricants and service parts that Citroën recommends. He will cross reference with other makes and brands to make sure he uses nothing but the best. He uses Total Quartz oil, Mann filters, Michelin tyres, etc. The car responds well and it drives and handles like it should.
From what we have researched, it appears possible that a well looked after 1.6hdi engine can last 200k miles and beyond. Look for yourself, there are many examples for sale with mileage way in excess of that.
Hope this helps.
Driveway Dudes Paul
Thank you i value all that you have told me im using the same oil and filter thank you tyres will come later on ,Paul.
Can it be fixed or would it need replacing ?
Would I spray the same place with fiesta 2006 tdci?
In the new 308 t9 1.6 ehdi is the procedure the same??
Can you tell me how to do this on a 2008 vauxhall combo van 1.3
My car doesn’t seem to run when I take the air mainifold piece off any reason ?
Hi, Thanks for your video at first.
My citroen c4 1.6 HDI have a faulty code P0409 issue on EGR valve.
Is that good to try this easy method to clean the egr valve?
OR,
I have to remove it to clean or replace the egr valve?
Best to remove the egr valve to be honest
I have a 93 Lincoln Town Car it's saying EGR valve high voltage EGR valve low voltage do you have any idea what I could be dealing with?
Not familiar with the 93 Lincoln Town car but try this link and it may help

What's the best thing that cleans out the carbon because I'm tired of Chrysler Dodge hinting at me that they're the only ones that can do it?
Question on this insertion location, how can this work when the EGR valve is not in the air intake flow? It is only in the Exhaust gas flow, EGR valve, then to the "intake manifold"? For this to work it must go through the engine fuel burning process then a rather small percent of the "cleaner" to do what you want it to do. Seems rather chancy for it to work at all? regards
Hi LLuE88,
It does seem a bit of a waste alright. Maybe only a small % is actually needed.
As we understand, all egr cleaning sprays have similar application instruction.
We followed the printed instructions on this particular brand and it appears to work.
This is preventative maintenance and it works on this car. Rather pay €10 or €15 for a can that is effective than risk trying some other method that may or may not work and could end up being costly.
No doubt some time in the future the egr valve may have to be replaced (€200-€300+) but for the moment this is an inexpensive solution, if only temporary
Paul
That's fine, my main concern was the amount of time and knuckle busting it takes to remove only to clean the EGR valve, it's very close to having to partially lift out engine to get at the EGR valve. I will do as you have indicated, also have a syringe that's 1" in diameter, works great to pump the diaphragm up and down, regards thanks, regards
Some claim that they can remove the egr valve without too much difficulty. For them it may very well be located in a more accessible place on their cars, vans, trucks, etc.
This works for us and as you mentioned it would need a partial lift of the engine to access it directly.
In our case, an M6 type bolt and 2 jubilee clips will give us the access we need to enable us to carry out this simple straight-forward cleaning operation.
If an engine lift even partially was required then it wouldn't be considered a preventative maintenance operation that could be easily carried out by a diy enthusiast/s

Gentlemen a question i wish to add stronger headlight bulbs to our 2012 berlingo multispace as my night driving in the country is not good would you suggest a upgrade please
paul.
Hi Paul. Good question. Personally I always found the headlights on my C4 effective as I've ensured that the headlight's exterior remains clean, the headlights are aligned correctly and I use the recommended bulbs from well known brands.
A useful online tool I use to find out what bulbs cars should have fitted is by Hella:
www.hella.com/MicroSite/bulbs/en/index.html
I recommend that you review your service history to check when the headlight alignment was last done (if ever) and if you think your Berlingo would benefit from it, to book it in to be done by a local garage. As always, some research on recommended brands & models of bulbs to suit your Berlingo will pay dividends.
***We are not affiliated with Hella****
Thank you so much ,this i will do, however i should have said im 83 years so driving at night or in the dusk is now dangerous for me so i avoid it ,paul.
Elizabeth McGovern Nice to see that elderly people also use UA-cam.
I do not know anything about Diesel engines. I have very small amount of amateur knowledge on gasoline engine. Silly question: from this video, it appears the spray is introduced at the turbo’s fresh air intake. This means the spray would travel through turbo, gets with compressed fresh air, thru inter cooler, into the fresh sore intake valves on the engine’s intake manifold, and into the cylinders to get burnt. On its way out, when already as soot and CO2, some of it (no more spray) might get into the EGR valve when the valve actuated.
In other words, probably less than 1% of the spray would get onto the gunk at the EGR valve?
Am I not understanding something correctly?
The turbo function is forced induction. A % of the egr cleaner spray would not pass through the egr valve though some may.
To say you know nothing of diesel engines then to say probably less than 1% would is quite a strange statement.
We cannot say for certain what percentage does get to the EGR valve but we can say for certain that it does indeed work when applied with this car
Driveway Dudes
Thank you for your reply, although it is not answering the root of my question.
I understand turbo charger is compressing air; that part is same as in a turbocharged gasoline engine. The difference is Diesel engine must have one, whereas gasoline engine could work naturally aspirated.
My question is: the post-turbo air need to enter the cylinder first, get combusted (so the cleaner is now mostly burned up, becomes CO2 and H2O and whatever other incomplete combustion compounds), go out the exhaust valve into the exhaust manifold.
At this point, there is very little “cleaner” left; most if not all should have being burnt.
Now: the EGR isn’t always on.
I don’t know what % of time an EGR valve would be on.
But when the EGR is on, then a fraction of the exhaust gas gets recirc’ed.
So we’re talking about fraction (after burning) of fraction (if EGR is on) of fraction (not all exhaust gas is recirc’ed even if EGR is on) of the cleaner spray would route through the EGR valve.
And we haven’t even got started on exhaust temperature being higher, so any lucky residual cleaner should be in gas phase not liquid phase, and doesn’t “clean” as well when in gas phase...
So back to my question: this method of cleaning EGR doesn’t seem to make sense.
Am I missing something here?
Or is there some keyboard hero who self-appoints as driveway/car expert can help enlighten us all?
Hi, Can i do this to my VW Transporter van 2.0 Diesel? Had a diagnostics which has come back with EGR Fault, engine management light is on. I also heard that you can put a certain EGR cleaner direct into the fuel tank when half full?
Is it a T5 or 5.1?
Usually injector cleaner is added to fuel in tank.
It's not uncommon for the T5 and 5.1 to have egr issues. You can try cleaning it yourself or removing the egr to clean it. That way you can give it a thorough clean whilst checking the vacuum actuator and connecting pipes and hoses.
If the van is not too old then in some cases as a gesture of 'Good Will' VW will replace the egr free of charge but you may have to pay labour costs
Hi, thanks for the video seem like i can learn alot from your videos. I have same c4.
Facing really strange issue with mine hoping if you could help me out with it.
It drives then after about 100 km it says anti pollution faulty and dies while driving and doesn't start again. Then the next morning it starts and does the same. Its has started recently as there was anti pollution fault before but never did this only would go to limp mode.
Took it to mechanic to see what fault was it.
It only showed turbo revolution pressure low.
But unfortunately the engine light wasn't on at that time perhaps that's the reason nothing else came on.
Quick reply will be really helpful as no mechanic wants to solve my issue as they say its Citroën it will do like this and i am stuck paying recovery alot of money
Forgit to mention when that happens the engine cranks but wont start. Starter and battery are good. some times it does start out of the blue, some times doesn't. Electric or mechanical so confused :( i was thinking to change fuel filter to start with and spray the egr valve?
Hi, Your description indicates that it may be the EGR valve not operating correctly, getting jammed open/closed
Spraying it with EGR valve cleaner may help
@@DrivewayDudes thanks will try that
Gentlemen Good Morning i hope you are both keeping well,some information please on my 2012 Multispace Plus 1-6 HDi which i love lately the back washer starts working of its own accord no input from me please can you advise me ?.-keep safe Paul.
Intermittent electrical issues can be a headache.
It sounds like you have a short. It could be at the switch, loose connector, the wiring loom or the washer motor.
Have you had an OBD/EOBD scan carried out to determine if there is a recorded fault code? If you have and there's no code then it looks like it's a process of elimination, fault finding physically and visually
Thank you so much you men are Jewels ,Paul
Got a 2.0 HDi Peugeot Expert. Starts fine (cept when very cold) and drives well but sometimes as I come to brake on an upward incline the engine stalls. It happens at one particular road almost all the time. Rest of the time fine. Any ideas? Thanks!
Hi V T,
Very cold/freezing weather can affect the performance of the battery and heater plugs. It can also affect the viscosity of oils including diesel especially if the engine has not been started for several hours.
Does it stall as you're braking or when you try to accelerate after braking and is the engine still cold when this happens?
Are there any warning lights on the dash prior or after?
What's the mileage on it?
When was it serviced last?
Have you had a diagnostics scan carried out?
Did you try cleaning the egr valve as shown in our video?
I service it myself. Oil and filters all changed regularly. Changed fuel filter recently. No warning lights and nothing on code scanner. 100k on the clock.
It stalls as I brake and come to a stop. The engine has been running for 20 minutes at least so not cold as such. I'll try the EGR cleaning and see if that helps. If it stops raining! Cheers.
My missus has the 1.6hdi but if she were to have another I would get 2.0.
Is anybody using a tuning box with success?
Do you think this method can be used to clean the EGR cooler on my 2009 Duramax in my GMC?
If the pipework layout is similar them we don't see why not
Hello Driveway Dudes :)
Some advice would be lovely!
I was driving my Peugeot 208 today, as I left a roundabout the car shuddered and the check engine light came on. Now having trouble accelerating at low gears. The car will start easily, but when I put it in first gear, it has trouble actually pulling the car. If I move to second gear at 10 miles per hour it has trouble gaining speed again. Similar changing to third gear at appx 20 miles per hour, trouble gaining speed. It's like it doesn't have enough power.
We have disconnected the battery and let the car reset. It will run fine for a few minutes, but when I reach appx 20-25 mph the issue occurs again.
Another strange thing that happened at the same time is that when I turn off the engine, the fan continues to run until we disconnect the battery.
It is a Peugeot 208, petrol, 1.4, 2013 plate.
Thanks xxx
Hi AtemsGal,
The 208 is a good car but like most cars can be prone to faults, be they minor or more serious.
Ideally you would need to get it checked and scanned by an approved garage so that any faults that are recorded on the cars ECU will show up.
We have heard of various reports of issues with 207 and 208 models similar to your issue.
The most common reports are - slipping clutch, coil pack, a fuel injector, dirty fuel, overdue service, failing alternator, etc
A replacement clutch or coil pack is expensive, an injector or alternator less. Dirty fuel can be drained. Service costs would depend on where you were to bring it.
Very seldom will a scan not locate the issue.
I would repeat above, Please have it checked by an approved garage.
Hope this helps.
Paul
Driveway Dudes Hi Paul thanks for the advice :)
Took it to the garage today. They said the coil pack was damaged and it had, in turn, damaged the spark plugs.
£180, not too bad. Thought it would be much more with how the car was reacting!
Thanks again :) xxx
Hi again i am again looking for your advice please cleaning the berlingo cloth seats which are badly stained and a very dirty engine bay full of dust its filthy but no oil leaks TG Thank you,Paul.
We have used upholstery spray foam cleaner. Very inexpensive and quite effective. Purchased in the £ shop or for the millenials, € shop
The engine bay is a trickier decision.
Option 1. Power wash it but make sure the engine is not running or too hot and avoid spraying directly on electrics.
Option 2. Hand clean with degreaser and hand wash off.
Option 3. Do nothing
if It's Stuck CLOSED,This Way Isn't Going to Clean it Well Enough to OPEN IT BACK UP.MY 05 SONATA Was So Bad ,Had to Be Removed & Soaked in Cleaner for Quite Some Time & Then Cleaned W/ A Wire Brush.Ur Basically Cleaning the Throtle Intake More Than the EGR VALVE.
Hi Tfc Tfc,
Thanks for your comment.
This video is for DIY maintenance on a working EGR valve to maintain optimal performance/operation.
If an EGR valve becomes faulty this would be the first step to carry out then if no joy it may have to be removed and repaired or replaced if necessary.
We have carried out this procedure on several vehicles in the past and found it worked satisfactorily.
We will definitely consider making a video of an EGR valve removal in the future.
Thanks.
Driveway Dudes - Paul
Didn't Realize It Was A Turbo Diesel Till I Saw All the Posts.
Now, now, child. Play nice.
sao không dịch sang tiếng việt đi bác
What is the spray being used
Very nice
How do you if you cleaned it ? you cannot see inside can you ?
So you didn’t clean the EGR! Just sprayed a cleaner fluid into the turbo
Looking to replace the valve on my nephews 2017 Nissan Juke Nismo, any suggestions?
Ahhh sure just replace the nephews.
On a Ford, if you get codes about EGR Pos. Sensors, replace the charcoal canister purge valve if it has one. If you get codes about Ox.sensor running rich, replace the MAP sensor.
Hi Marty. Good to know and noted :) Thanks
Hi guys, my wife’s C4 GP 1.6 hdi is showing an engine management light and an ‘anti pollution faulty’ message. The car is driving ok up to 80 kph /50 mph but after that it can slow down going up hill, can hold back in traffic or even stall when going around a corner. Is it worth trying this treatment or is it altogether more serious? I’ve also thought about changing the fuel filter and air filter but then I’m stuck for ideas after that. Thanks for the great videos, they’re really inspirational.
Hi robru,
It could be a partially clogged EGR valve or it could be a clogged DPF.
If the fuel filter was bad, the car may have starting and acceleration issues at all speeds including stalling as well as pushing out excessive exhaust smoke.
Cleaning the EGR valve with the spray would be the first and least expensive step in a process of elimination.
Hope this helps.
Driveway Dudes many thanks for replying. I will give the spray a try first.
I just bought bmw 3 series 2010 disel the milage are 185k and it showing engine light i asked macsnic its egr prob.
Shall i call the company who come and clean the full system the EGR valve, MANIFIOLD, and the rest fuel injectorts the whole system by ataching some pipes to engine and clean full carbon which is stuck inside
Will that solve the egr prob's
Any one can help plz.
Hi i hope you are both keeping well ,some advice please on our Multispace Berlingo 1.6 HDi when i lock the steering to reverse right or the same forward i can feel a vibration coming back through the steering ,what do i need to get fixed please this started after we hit a huge pothole filled with rain ,thank you paul D.
Hi,
Hitting potholes can indeed cause steering issues, e.g. damage to tyre, damage to wheel, steering mis-alignment, suspension, etc.
We would recommend you bring it to a reputable tyre garage to have the tyre, wheel and tracking/wheel alignment checked. If you decide to have it tracked/aligned you may find it has resolved the issue. If not, then you may need to further investigate.
Thank you yet again we did as you have suggest but tyres and tracking were all ok he could not find a problem ? hence im annoying you Gentlemen once again Sorry paul
No need to be sorry and you're not annoying us. We're happy to help :) It could be a drop link, tie rod end, balljoint, wishbone bushing, suspension top mount, damaged spring, leaking damper/shock, engine mount, etc on either or both sides.
It would be best to bring it to a mechanic or garage that is familiar with the brand
Thank you will Do Happy weekend Gents paul.
Thanks and you too.
Would this procedure apply to a petrol car? I am thinking in particular of a 2009 Chevrolet Matiz. Good work, many thanks!
In case of your car, it is petrol car with no turbo I guess. I that case, the inlet manifold of petrol car does not get much dirty.
I had the problem a couple of months ago when engine running when very lumpy and yellow engine management light came on. I gapped plugs, changed coil-pack but no good. I later replaced spark plugs but though running a little better, that was not full answer. I cleaned PCV which seemed to be working OK then reoved air-hose and squirted cleaner into air-intake. Within a couple of squirts, engine came back to running normally. For good measure, I fitted new air-filter as this was noticeably nearly black and likely overdue. Finally, yellow engine management light went out without having to cancel anything and everything still works just fine having passed annual technical test with no problem! Have a good day!@@salimmetin
My vw golf has limp mode sometimes what's the best solution clean EGR valve and hopefully ready to go 👍
If you have access to a car scanner then try that and see what faults are showing up before attempting anything further
Driveway dudes.....awesome name
👍
please which oil for the gearbox in a Multispace 1.6 HDi 90 2011 135000 miles it is manual 5 speed a bit of a whine when you let it coast in gear less so when you are accelerating thank you paul.

Thank you very much Paul.
I wonder if the Wynn's catalytic converter and lambda oxygen cleaner would work on a EGR valve
If addid to the petrol tank.
Just a thought.
Nothing added to the fuel tank will have any effect on the EGR. It needs to be though the air intake system.
I'm a mechanical engineer and doing this achieves nothing. You have to take the egr off and do a proper job.
But this method works, I know because I tried it with Mr muscle on my picasso.
And most of the mess goes inside the intake manifold
It does work done it myself, had no issues or fault codes since, but I did use EGR cleaner not Mr Muscle lol.
You cannot clean the EGR valve without hydrogen carbon cleaning it. The mechanic that says he will do it is full of it. Trust me. That black coal like gunk won't come out.
Definitely works, I used a mix of mould remover and fly spray on my Ferrari 355
Hi Driveway Dudes. I have a peugeot 307 SW HDI 1.6, it is a 2004 model. My car has started bunrning the engine oil and it is producing a lot o smoke. Everybody wonders when I drive a round because of smoke. Can thing be solved by cleaning the EGR Valve, Inlet Manifold and Inlet Valves using the EGR cleaner?
It's probably the cheapest first step to try. If it works then you've solved it. If not, then you have gotten one step closer to finding the issue by ruling that out
Can you use this method to clean dpf on my Peugeot 407 hdi 2.0 ?
A clogged or jammed egr valve can affect the dpf. Cleaning the egr may help
